Gestion du pâturage au printemps en système bovin allaitant : diversité des pratiques en Saône-et-Loire

2009

National audience; Grazed grass is the cheapest forage for making meat'. In order to incite farmers to make their forage systems more self-sufficient and thrifty, the 'Chambre d'Agriculture de Saone-et-Loire' (a professional agricultural organization for that departement) has been monitoring for five years the management of spring grazing on 23 farms. The analysis of farmers' practices lead to considerations as to put to the best use the grazed grass, according to the pedo-climatic conditions and the constraints of the farms. With the aim of optimizing the pasture resources in order to limit the purchase of concentrates and to cope with the climatic hazards, the study of the management of s…

Place des prairies permanentes dans les élevages allaitants de Bourgogne, projet de recherche PSDR Bourgogne. Rapport final

2006

La diversité des communautés végétales des forêts alluviales de l’Allier est-elle affectée par l’invasion de l’Érable négundo, du Robinier faux-acaci…

2012

Identifiant ProdInra 270418 SPE EcolDur CT3; Master; L’objectif de notre étude a été d’analyser les effets de l’invasion de 3 espèces végétales (Érable négundo, Robinier faux-acacia, Renouée de Bohême) sur la diversité spécifique et fonctionnelle ainsi que sur la structure et la composition spécifique des communautés végétales des forêts alluviales de l’Allier. Des relevés de végétation ont été réalisés dans des paires de quadrats contiguës, envahis et non envahis par les 3 espèces invasives étudiées et dans 3 habitats envahis des forêts alluviales de l’Allier (Saulaie-peupleraie de niveau topographique haut et bas et Chênaie pédonculée-ormaie). Complémentairement à cette approche, un gradi…

Different Medicago truncatula genotypes, expressing different phenotypes, modulate microbial functional genes in the rhizosphere

2022

Plants host in their rhizosphere a remarkable diversity of microorganisms that in return promote plant growth and health. Thus, the plant microbiota emerges as a novel component that expand the capacity of plants to adapt to the environment, and thus pave the way for future breeding approaches.It is widely known that different plant species harbor different microbiota, but very few studies showed an impact of the plant genotypes on the microbiota. These contrasting results may depend on the choice of the tested genotypes.We formulate the hypothesis that only those plant genotypes showing high genetic diversity and expressing different phenotypes harbor different rhizosphere microbiota and a…

The "very loyal pinot": historical trajectory of a mythic grape variety of Burgundy

2019

Grape varieties began to appear in historical sources at the end of Middle Ages. In Burgundy, early mentions of pinot correspond to an evolution in the way wines were named. From the 14th century onwards, pinot wines have persistently demonstrated to express elements of superior quality. This variety is often offered at expensive prices due to the nature of its rarity, and as a result is commonly reserved explicity for the élites. However, it is suggested that the roles of The Dukes of Burgundy, concerning the promotion of grape varieties, is to be moderated. Therefore, if Philippe le Hardi’s proclamation condemns « the very bad and very disloyal plant called gaamez » then, it is evident th…

The standing of the Southern Côte-d’Or in the evolution of the early Iron Age funeral practices in Burgundy and Franche-Comté

2014

This work is a synthesis of tumuli graves in Burgundy and Franche-Comté from Hallstatt C to La Tene B periods. The objective is to characterize the funeral assemblages in Southern Côte-d’Or as well as the influences and the tendencies that went through this area during the early Iron Age. A set of comparisons shows the particularities of the Southern Côte-d’Or at several levels: the recruitment of the populations, the position and orientation of the deceased, the architecture of the graves and their internal arrangements, the typology and positions of the personals items, the nature and locations of the deposits. These various leads allow reconstituting costumes and mortuary practices, as w…

The use of Burgundy stone from ancient times to the present day

2014

International audience; Burgundy stone is widely reputed for its quality and diversity. Because it is suitable for the various requirements of construction and sculpture, it has been used continuously since ancient times. Inventories drawn up so far by researchers have been piecemeal. A new comprehensive inventory has now been undertaken with a view to renewing the involvement of various academic disciplines (archaeology and history of architecture, socio-economic history and history of art). A partnership has been formed among various laboratories at the University of Burgundy in order to ensure the validity of archaeological and historical data, develop an open platform in the form of a W…

Crémations et monument funéraire campaniformes à Genlis « le Nicolot » (Côte-d'Or, France)

2021

The building of the high-speed rail track linking the Rhine to the Rhone led to the discovery of two Bell Beaker burials in an Iron Age cemetery located in the plain to the east of Dijon. The Tilles plain is an alluvial environment, shaped by the valleys of the Tille and the Ouche and populated since Late Prehistory, particularly during the Bell Beaker and Early Bronze periods, which have yielded settlements located on the rivers. These burials are the first funerary features discovered in the area.The two Bell Beaker cremation burials excavated at Genlis "le Nicolot" are remarkable, as still too little is known of the funerary practices of the period in the east of France and in particular…

Appearance and use of Roman roofing materials in the region of the Aedui and Lingones

2014

Römische Konstruktionstechniken und Baustoffe können als Anzeichen für Romanisierung gewertet werden. Sie legenZeugnis von den veränderten Verhaltensweisen ab, wie die Haeduer und die Lingonen mit den natürlichen Ressourcenumgingen, um diese Materialien zu produzieren. Es können deutliche Unterschiede zwischen diesen beiden gallischenStämmen hinsichtlich des Einsatzes von Ziegel- und Steindächern beobachtet werden. Die Haeduer verwenden meistensZiegel für ihre Dächer, selbst wenn die lokal verfügbaren natürlichen Ressourcen eine Produktion dieses Baustoffesnicht erlauben. Im Gegensatz dazu kommen bei den Lingonen Ziegel nur dann zum Einsatz, wenn die entsprechendenRessourcen vorhanden …

Vineyard soils and landscapes of the Burgundy Côte (France): a historical construction worth preserving

2012

International audience; The construction of vineyard landscapes along the Burgundy Côte is the result of geological processes and of human labour. Substratum diversity in this vineyard is the result of a very long history explained by the diversity of Jurassic sedimentary facies and Tertiary tectonic activity. The nature and thickness of Quaternary deposits (Weichselian scree debris and alluvial fans) reflect sediment dynamics concurrent with the last glaciation. As soon as humans started to occupy and cultivate these slopes, the changes they made in the land through crop development and roads began to structure the vineyard plots in a lasting way. The footprint of vine work in soils can be…
